Answer:
Median =17
Step-by-step explanation:
Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet.
Let X be the height of a randomly selected adult giraffe.
X is a random variable.
a) X is N(17, 0.9)
b) Median giraffe height = 17 ft since in normal distribution mean = median
c) When x = 18.5, Z = 
d) 
e) 
f) 75th percentile for z is 0.675

Answer: 
Step-by-step explanation:
The total outcomes on a die = {1,2,3,4,5,6}=6
The total outcomes on a coin = {Tails or Heads}=2
The number of possible outcomes =
If you roll one die and flip one coin, then the possible outcomes are:

Here T denotes for Tails and H denotes for heads.
The to the question is acute
